COLUMN PIPE

Ajay Hose is all-purpose suction and discharge flexible hoses with rigid PVC spiral. It is a lightweight suction and delivery hose, which has a specially compounded PVC reinforcement, which is helically wound and inseparably fused to the soft inner walls. The structural composition of the walls so formed is ideal for withstanding multi-axial stress under load.

SPECIFICATIONS

-Maximum Installation Depth: 370 meters
-Installation: Vertical, Horizontal or inclined
-Maximum ambient temperature: 70°C

APPLICATIONS

-Water rising for submersible and jet pump for irrigation, domestic, industrial mining, chemical distribution etc.
-WA good substitute for MS, ERW, GI, HDPE & SS column pipes.
-WAjay uPVC Column Pipes are nearly inert towards corrosion, chemical reaction and erosion. Hence, it is ideally suited for long term use in salty, sandy and chemically aggressive water.

TECHINICAL FEATURES OF AJAY UPVC RISER / DROP /COLUMN PIPES

The pipes are joined together by a coupler. The couplers are fitted on the pipe sizes from 33mm OD (1″) up to 140mm OD (5″).

The joint of pipes have been specially designed with square threads to ensure proper gripping and no chance of slipping. These threads are high friction threads, which do not open even on constant forward and reverse torque generated by starting & stopping the pump. They are made on special CNC machines with high accuracy tools to ensure perfect dimensions and good & easy fitment. All threads are checked thoroughly with gauges to ensure 100% accuracy.

An outer rubber ring is provided on one side of the pipe and an inner rubber ring is provided in the Socket side of the pipe, which ensures a 100% leak proof joint.

We have developed a unique Bi-axial orientation technique used during pipe extrusion, which gives higher drop impact and notch impact strength to the pipes. This orientation technique is a result of our constant Research and Development.

This is an innovative technique for making pipes thicker on the threading end to compensate for material removal due to threads. The residual thickness in the end part after removal of thread is the same as pipe thickness, Therefore the pipe strength remains the same. This technique provides much higher strength to the pipes.

A proper combination of perfect uPVC is made with the adequate & specially designed formulation of resin, heat stabilizers, lubricants, processing aids, impact modifiers and essential additives. All ingredients and process parameters taken in the correct proportion, results into increased impact and tensile strengths. As a result, pipes are capable of handling both internal hydro static pressure as well as vertical tensile load on the pipes due to the column water and pump weight. The special formulation ensures that the threads do not break / chip even after loosening and tightening several times during the life time.

AJAY Drop / Riser pipes have a dual function to perform. On one hand it has to withstand the pump delivery hydro static pressure, which is maximum in the first pipe connected to the pump and may be as high as 35 Kg / cm2 and on the other hand, the top most pipe bears the load of the entire column filled with water & pump which may range up to 2 Metric tons. This dual type of loading application makes this product unique and requires special manufacturing techniques which are available only with us.

AJAY UPVC RISER/DROP/COLUMN PIPES ARE PERFECT REPLACEMENT TO CONVENTIONAL GALVANIZED IRON PIPES USED IN BORE WELLS AND HOLD SEVERAL CRITICAL ADVANTAGES OVER CONVENTIONAL MILD STEEL OR GALVANIZED STEEL PIPES, WHICH ARE

ADOPTERS (CONNECTORS)

Ajay certified high quality Adopters (both top & bottom) Made of Cast Iron (CI) / Mild Steel (MS) / Stainless Steel (SS) used with Ajay Column Pipes give true & corrosion proof system.

PUMP GUARD

Pump Guard can be used between bottom pipe & bottom adaptor (connector). Pump guard is recommended for the areas where excessive pump viberations are observed.
